Analysis of Mapping of Water Resistance Zoning for Groundwater Protection Areas (Groundwater) PDAM Tirtanadi Sibolangit Deli Serdang Regency, North Sumatra Province

Introduction

Indonesia's Natural Wealth and Water Resources

Indonesia is renowned for its rich natural wealth and abundant biodiversity, encompassing a wide range of flora and fauna. The country is also blessed with numerous water sources, both from shallow and deeper groundwater. However, despite this comfortable condition, the community is not entirely free from environmental problems, particularly in terms of damage to water catchment areas. The high utilization and exploitation of groundwater, as carried out by the PDAM (Regional Water Supply Company) of Tirtanadi in Sibolangit, have led to a crisis in the management of water resources. With more than 24 water collection points in 24 hours, and the presence of other companies such as PT. Aqua Danone, which operates upstream, this has caused concern about the impact of exploration on the sustainability of groundwater sources, which has the potential to cause a lack of clean water for around 4.2 million people each year.

Background of the Study

Groundwater Infiltration Zoning for Water Resource Protection

This study aims to analyze groundwater infiltration zoning for the protection of water resources in the Sibolangit area. Descriptive methods are used to collect data factually in the field, with purposive sampling sampling techniques that ensure the location taken is an area that contributes to water catchment. Samples are taken from 10 points by considering the uniformity of geological maps, soil types, topography, hydrogeology, land systems, and land cover on a scale of 1: 50,000.

Methodology

Data Collection and Analysis

The results showed that the topographic, geological, and hydrogeological factors had a significant effect on determining the water catchment zone. Meanwhile, other factors such as infiltration, permeability, bulk density, rainfall, and land management also contribute to the quantity of water catchment areas. For example, the infiltration value ranging from 9.93 - 14.16 cm/hour indicates that the water infiltration process is very good. In addition, percolation with a value between 2.35 - 3.43 cm/hour also shows a good level after observation for one hour in the field.

Results

Laboratory Testing and Landsat Map Analysis

Laboratory testing further revealed that the permeability value ranges from 0.35 - 20.54 cm/hour indicating permeability that varies from medium to good, while the bulk density is measured between 0.37 - 0.82 gr/cm³ indicates an optimal density for support water catchment. Rainfall data obtained ranges from 1,857 - 4,243.5 mm/year reflects a high enough rainy level, which is an important factor in the water catchment process.

Landsat map analysis also revealed that land cover conditions and land management are currently still in the good category. This is a supporting factor for the sustainability of water resources in the region, although sustainable management challenges must continue to be faced.

Conclusion

Importance of Water Resource Protection

Taking into account all the results of this analysis, it is essential for policy makers and the community to be more concerned with the protection of water resources, with concrete steps in sustainable management. Awareness and proactive actions in protecting water catchment areas can guarantee the availability of clean water for future generations.

Recommendations

Policy and Community Action

Sustainable Management: Implement sustainable management practices to ensure the long-term availability of clean water.
Awareness and Education: Raise awareness and educate the community about the importance of water resource protection.
Monitoring and Evaluation: Regularly monitor and evaluate the effectiveness of water resource management practices.
Collaboration and Partnership: Foster collaboration and partnership among stakeholders to ensure the protection of water resources.

By implementing these recommendations, we can ensure the sustainability of water resources in the Sibolangit area and provide clean water for future generations.
